When we look out at the universe we see an enormous expanse full of objects like stars, the earth, everyday matter, us. What are all these objects made of? We know that deep down there are atoms, which in turn are made of electrons and nuclei, the latter being composed of nucleons (neutrons and protons). What are nucleons made of? They are made of up and down quarks. These two quarks together with electrons and electron neutrinos make up the first generation of particles. There are two other generations whose particles are heavier versions of these four. The electrically charged particles interact electromagnetically due to photon exchange, the quarks are glued together with gluons and radioactivity occurs due to W and Z boson exchange. To complete this picture (called the Standard Model) we need the Higgs particle.
So what's wrong with this Standard Model? There are many problems. First of all, the Higgs has not been observed experimentally, and it seems to have been introduced in an ad hoc fashion into the model. It gives particles their mass, but is that truly the origin of mass? And if so, how do we explain that fundamental particle masses are so small compared to unification energy scales? And how do we explain the range of masses? Why are there 19 + 7(?) + 9 + parameters in a fundamental theory? Is there really a Grand Unified Theory (GUT) that unifies known forces? How do we explain flavors, generations and so on?
In addition to questions about the Standard Model, there are further questions. Are there extra spacetime dimensions? If so, black holes should be produced at high energy in the lab. Stabilizing the mass of the Higgs requires some new mechanism, perhaps supersymmetry. And what about the widely proclaimed String Theory? Is it real?
We plan to look for answers to all these questions on the ATLAS detector at the LHC. We will search for supersymmetry and other kinds of new physics.
